Sir Ken Robinson, PhD, is an internationally recognized leader in the development of creativity, innovation and human resources.
A while ago he did a few TED talks called “Do schools kill creativity?“, “Changing Education Paradigms” and “Bring on the learning revolution!”
This is another one of his talks, it is the TEDxLondon – Outro:
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the moon and the sun and the rotation of the Earth. See:
Chris Lehmann introduces a revolutionary idea in education: Encourage learning by allowing students to do things they are good at instead of restricting them.
Not long ago I told you that YouTube is popular. They still are!
According to figures released by Google today one hour of video is now being uploaded to Youtube every single second of the day! That upload rate – equivalent to 60 hours per minute – is an astonishing tenfold increase from its 2007 video upload rate.
And some 30 per cent of its growth has come in the last eight months, says Google. Just for fun, they’ve posted an animation called onehourpersecond.com to show you just what happens in a Youtube-upload-second – and multiples thereof.
Every month or so, the astronauts at the International Space Station capture Earth in the most amazing, astonishing, rock-your-socks-off way imaginable.
This video shows Africa’s lightning storms and something else: the Milky Way rising over the horizon. Captured on December 29, 2011, it shows a pass from over central Africa, near southeast Niger, to the South Indian Ocean, southeast of Madagascar.
Cool!
The brains of children raised in violent families resemble the brains of soldiers exposed to combat, psychologists say.
They’re primed to perceive threat and anticipate pain, adaptations that may be helpful in abusive environments but produce long-term problems with stress and anxiety.
For them to detect early cues that might signal danger is adaptive. It allows them to react, to try and avoid the danger. However, a very similar neural signature characterizes quite a few anxiety disorders. Learn more here.
“Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines. Catch the trade winds in your sails. Explore. Dream. Discover.”

It’s remotely possible the world will end in December 2012. But don’t credit the ancient Maya calendar for predicting it, say experts on the Mesoamerican culture.
It’s true that the so-called long-count calendar—which spans roughly 5,125 years starting in 3114 B.C.—reaches the end of a cycle on December 21, 2012.
That day brings to a close the 13th Bak’tun, an almost 400-year period in the Maya long-count calendar.
But rather than moving to the next Bak’tun, the calendar will reset at the end of the 13th cycle, akin to the way a 1960s automobile would click over at mile 99,999.9 and reset to zero.
“We, of course, know that really means a hundred thousand miles and not zero,” said William Saturno, an expert on Maya archaeology at Boston University.
“So, is the end of Bak’tun 13 a large period ending? Yes. Did the Maya like period endings? Yes,” Saturno said.
“Would this have been a period ending they thought was wicked cool? You bet. The biggest period endings they experience are Bak’tun endings.”
But “was it predicted to be the end the world? No. That’s just us.”
Instead, for the Maya, the end of the long count represents the end of an old cycle and the beginning of a new one. So maybe 2013 will be a time when wicked cool things start to happen – flying cars and stuff !!! Learn more here.
